i had the same problem. i drive a 95 so im not sure if it differs from were the fuse box is. look righ above you pedals to your far left. it should be right there. also if you instruments went out it will be a 15 fuse. its a blue fuse. next my panel went out cuz of the wires on my transmission. if yor looking at your jeep at the front. the wires will be on your left. make sure they are not burned or anything. it will be right on the side of your tranny. mind got burned by the exaust so they were shorting. check that is and see if that is what is it. for a temp fix just put some electrical tap around the wires and you should be set for a wile. good luck

Try this disconnect the heater hoses from the heater core use a hose to backflush the core. Then reconnect and try again.

You have two locations for the fuse box. One is either under the hood or behind the glove box. I would pull apart the glove box and take a look.

is it the straight six? if so first disconnect the battery then there should be 2 bolt 13 or 14 mm. take wires off. then reverse for install.

Sounds like the blend door that diverts air flow inside the heater box is not working, or, the heater control valve on the heater hoses in the engine bay is not closing.
